13 Claims. (01. 164118) or stacked. relation and have means such asbores for receiving'tool shanks, certain of the bores in. the, lowermostbody being preferably closed by the lower, face, of the uppermost bodywhereby the latter constitutes a. backing plate for tool hanksreceivedin such bores, and another of the bores in the lowermost bodybeing in registration with a bore in the uppermost body wherebyr a.

longer tool shankmay. be received'in both of said bodies, f 1

Another objectis to provide a holder wherein meanslis'p'rovided in oneof said bodies for holding. toolshanks received within the bores in saidbody, andmeans is provided in the other of said hodiesifor, holdingfthetool shank received in Anotherfobject is to provide a holder whereinthe. retaining means in both bodies are accessible from the lower facesof the lowermost body.

Other. objects, advantages and novel details of i construction of thisinvention will be made more apparent as thisdes'cription proceeds,especially whenconsidered in connection with the accompanyingdrawings,;wherein: V

Figure. 8 is a plan view of the upper body Referring, nowto. the:drawings, 1 isthe plunger or rainwof a, punch press and 2 and 3respectively are cooperatingetool receiving bodiesof a holder atembodying my invention. As shown, the bodies 2 and 3 are arranged insuperposed relation and are secured by bolts 4 to the ram 1 of the punchpress. The upper body 2 has a singlevertic'al bore 5. that extendsvtherethrough and is closed at its upper'end' by a hardened backing plate6 interposedbetw'een the body 2 and ram 1, while the lower body 31 hasavertical bore '7 in alignment with the bore. and has a series. of'vertical bores 8 arranged in a circle about said bore 7,. preferablyconcentrically with respect thereto. Each of the last mentioned bores 8.extends through the lower body Band has its upper end. closed by thelower faceof the upper body. Ar ranged in another circle, preferablyconcentric with the bore. '7 and. the circle of holes 8', are shorterbores 9 that extend downwardly from the upper faceoi the lower body insubstantially parallel, relation to. the bores 8 andlterminate short ofthelower face 10 of'said body. Slots ll, substantially equal in depth.to the depth of the bores. 9 and having substantially parallel walls 12,and 13,.extendbetween and open into the bores 8 and 9,,ywhile relativelysmall bores 14 extend upwardly from the lower face of. the body 3to theslots 11' and are preferably parallel to the bores 8. Likewise-the upperbody 2 has a bore 15 that extends downwardly from-the upper faceofithe'body in substantially parallelrelation to the'bore' 5-and:terminates short of. the'lower face of thefbody. A' slot1'6substantially equal infdepth to the depth of the-bore l5 and havingsubstantially parallel-walls 17 and 18"respectively extends between'and'opens into the bores 5'and 15, while a relatively small bore19-extends-up wardly from the lower faceof the body 2' to'the slot lfi.As shown, thisbore 19 is parallel to the bore:.51 and is in alignmentwith a bore 20 of similar diameter. extending vertically throughthelower body 3...

Located within the bores 9 and15 are leverss22, coil springs 2V3-andsleeves-or bushings 24 similar to parts 14-, 2 0 and21 respectivelyillustrated in my pendingapplication aforesaid and constituting themeans for'retaining. the shanks 26 of punches withinthe bores 5, 7 and.8 respectively inthe bodies. As shown, thelevers 22. have sphericallower ends 27 journaled in rounded portions 28 and 29 respectively ofthe bodies 2' and 3'at the lowerends ofithe bores 9'and"'15,, extenddiagonal- 1y through the, slots'll and 16 respectively and havearcuateupper ends for engagement with the punch. shanks. 25. The, springbushings. 24 are fixed within the bores 9 and l5-respectively sons tohold-the spherical ends 27 of the levers within the roundedportions28and 29 respecthe arcuate ends 30 of the levers in the lowerbody 3 when the shanks 42 are inserted into the bores 8, while the shank45 of the long punch 41 is provided adjacent its upper end with anarcuate slot or groove 46 that is engaged by the arcuate end 30 of thelever in the upper body 2 when said shank 45 is inserted into thealigned bores 7 and 5. In this connection it willbe noted that thelevers have a propping action and hold the upper ends of the punchshanks 42 and 45 respectively against the backing plates 2 and 6. Anysuitable means such as anextractor pin 4'7 may be inserted inio the bore14 or into the aligned bores 19 and 20 to push the levers upwardlyagainst the tension of the springs to release the punches so'that theymay be withdrawn from the holder. Thus punches may be readilyinserted'in or withdrawn from the holder wiihouthaving to take it apartor separate it from the ram. v

In Figures 6 to 8 inclusive I have illustrated a slight modificationwherein the'bodies 50 and 51 respectively are rectangular infshape andeach 5 contains a plurality of punch shanks. As shown,

the upper body 51 has four bores 52 arranged in a row, while the lowerbody 50 has four bores 53 arranged in registration with the bores 52 inthe upper body and is provided upon opposite sides of said bores 53 withtwo rows of bores 54. The spring pressed levers 55 correspond to thelevers 22 and are located in bores 56' and 57 respectively at thesides'of the bores 52 and 54 for retaining engagement with the toolshanks 58 and 59 respectively. Likewise bores 60'are provided in thelower body 50 in alignment with the bores 5'7 for receiving theextractor pins (not shown) and registering extractor pin bores 61' and62 respectively ar'e'provided in the bodies '50 and 51 in alignment withthe bores 56.

While it is believed that from thef'foregoing description the nature andadvantages of the invention will be readily apparent, I desire, to haveit understood that I do not limit myself to what is herein shown anddescribed and that-such changes may beresorted to when desired as fallwithin the scope ofwhat is claimed. v

What I claim as my invention is: l.

3. A tool holder having two separable bodies arranged in superposedrelation and provided with aligned bores for receiving a tool shank, theuppermost body having means at one side of the bore therein forreceiving tool shank retaining means, said bodies having aligned boresfor receiving an actuating tool for such retaining means, the lower bodyhaving a plurality of bores extending from the bottom to the top thereofreceiving tool shanks, said bores being closed by the intermediatesection whereby the intermediate section serves as a seat or abutmentfor the tool shanks received within the bores, the lower andintermediate sections having aligned bores extending from'the bottom ofthe lower section to the top of the intermediate section for receiving alonger tool shank, the uppermost section extending over said alignedbores and serving as a seat or abutment for a tool shank receivedtherein, andindependent and automatically operable means in said lowerand intermediate sections for retaining tool shanks in said 5; A toolholder having upper and lower tool receiving bodies, the. lower bodybeing provided with a plurality of bores for receiving tool shanks, theupper body having a bore registering with one of the bores in the lowerbody, and serving as a backing plate for tool shanks in the other boresin the lower body, and means in the lll per body for retaining a toolshank in said aligned bores, no said retaining means being operable froma point below the lower body to release the shank in said registeringbores. r

6. A tool holder having a plurality of bodies arranged in superposedrelation and having registering bores for receiving a tool shank, thelowermost body having other tool shank receiving bores, means in saidlowermost body for holding the tool shanks in the last mentioned bores,and means in the other body for holding the .tool 1!) shank that isreceived in said registering bores, the means in both bodies beingoperable'from points below the lowermost body'to release the tool shanksin said bores.

7. A tool holder having an upper face attachable'to a ram of a punchpress and having vertically extending means openingthrough the lowerface of the holder and operable while theupper face is attached topermit the insertion upwardly into the holder through the lower facethereof of tool shanks of different lengths, and means for retainingthetool shanks in said holder, includ-- ing means located in differenthorizontal planes in the holder but accessible and operable from pointsbelow the lower face thereof to'permit the withdrawal of the tool shanksof different lengths through the lower face of the holder.
